Back in the late ’60’s (**** that’s a long time ago) my brother and I got our hands on a bike that had been dumped, stuffed the tyres with straw and then built a ‘ramp’ on some open ground near our parents.
Ramp was some bits of stone & broken bricks stacked up and a piece of wood as the ramp.
Even now i can feel the pain of crown jewels crashing into top tube as tyres didn’t work as intended and I discovered by bike handling skills were s**t.
And the ramp didn’t provide the hoped for elevation.
Other than that – it was great…………….
